1. A device to be used by a human subject comprising:
(a) a camera apparatus, comprising two cameras spaced a fixed distance apart, wherein each of the two cameras is configured to capture an image of a pair of human eyes on a human face for deriving dimensional measurements of the pair of human eyes on a human face, the device having established through trigonometric methods a ratio of known distance units to a plurality of pixels in the images generated by the two cameras, wherein the device uses the established ratio of known distance units to pixels and the images of the pair of human eyes to measure a distance between said human eyes on said human face, and the device, using a first known distance and a second known distance, having established a horizontal axis and a vertical axis for said camera apparatus, and wherein said first known distance, said second known distance, said horizontal axis, and said vertical axis allow said camera apparatus to compensate for zooming in or out relative to said human subject when imaging;
(b) a central processing unit and a memory, wherein said memory includes a software; and
(c) a display;
wherein said software and said central processing unit are configured to display a digital eyeglass frame on said display screen,
wherein said software and said central processing unit are configured to render said digital eyeglass frame with one or more of said images of said human face based on said distance between said pair of human eyes.
